Growth and high-resolution paleoenvironmental signals rhodoliths (coralline red algae): A new biogenic archive
We investigated rhodoliths (coralline red algae) from a subtropical ocality in the Gulf of California (Lithotharnniurn crassiusculurn) and a subarctic locality in Newfoundland (Lithotharnniurn glaciale) for their potential as paleoenvironmental rchives using microanalytical geochemical techniques tomeasure variations in ;5•80, Mg, and Ca. Rhodoliths are potentially well suited as recorders of s...
متن کاملPhenotypic plasticity of coralline algae in a High CO2 world
It is important to understand how marine calcifying organisms may acclimatize to ocean acidification to assess their survival over the coming century. We cultured the cold water coralline algae, Lithothamnion glaciale, under elevated pCO2 (408, 566, 770, and 1024 μatm) for 10 months. The results show that the cell (inter and intra) wall thickness is maintained, but there is a reduction in growt...
متن کاملDiversity, growth forms and rhodolith distribution: factors controlling the fabric of coralline algae of the early Miocene deposits, Cairo – Suez road, Egypt
The Lower Miocene deposits in Gabal Gharra, Cairo – Suez District, unconformably overlies the Oligocene and Eocene deposits. They consist predominantly of regressive and transgressive mixed siliciclastic / carbonate sediments of shallow marine environments. The Lower Miocene deposits are represented lithostratigraphically by the Gharra Formation that comprises four members, from base to top: Ag...
متن کاملHollow rhodoliths increase Svalbard's shelf biodiversity
Rhodoliths are coralline red algal assemblages that commonly occur in marine habitats from the tropics to polar latitudes. They form rigid structures of high-magnesium calcite and have a good fossil record. Here I show that rhodoliths are ecosystem engineers in a high Arctic environment that increase local biodiversity by providing habitat. Gouged by boring mussels, originally solid rhodoliths ...
